c# - IBM.Data.DB2.DB2Trace.Entity_CheckDB2Trace()

Question

我想使用 VS2015 连接到 DB2 数据库，但收到错误消息。我可以使用工具连接到 DB2，并且我的连接信息是真实的。在我的代码中，我试图将记录保存到 DB2 数据库中，但出现以下错误。

网络配置：

<entityFramework>
    <providers>
      <provider invariantName="IBM.Data.DB2" type="IBM.Data.DB2.EntityFramework.DB2ProviderServices, IBM.Data.DB2.EntityFramework, Version=10.5.5.6, Culture=neutral, PublicKeyToken=7c307b91aa13d208" />
    </providers>
  </entityFramework>

连接字符串：

 <add name="ExportModuleContext" connectionString="Server=dv0bdb2:446;Database=DV0BPLOC;UID=UDISAP;PWD=12526b;" providerName="IBM.Data.DB2" />

我的错误是：
